Thanks for the offer Luke, But I'll have to decline.
the brake upgrade uses XT130 struts and hubs, RA60 discs (258x20) and MX62 single piston calipers.
The reason the MX62 calipers are used is because the Sumitomo twin piston caliper would need a spacer plate to fit over the wider disc.
Luc reckons his MX62 rotors are 2" bigger than std KE30 brakes, and these have another 10mm over the MX62's.
